This invention relates to improvements in 'means for applying cooling iiuid t0 the internal surface of a bottle, jar or other hollow glass article to effect cooling thereof, as in tempering such an article.

An object of the invention is to provide a spray nozzle constructed and arranged to discharge jets of gaseous fluid-liquid spray into one part of a hollow glass article and jets of a different coolant, as gaseous vfluid alone, into another part of the glass article.

-Another object of the invention is to provide a nozzle of the character described by which part of a supply stream of air is mixed with lliquid Aspray andthe resultant spray product is con- Aducted to jet holes in the lower part of a hollow 'glass article that is to be cooled while another .part ofthe air supply stream is conducted to jet holes for discharging jets'of the air into lthe up- .per'part of the glass article.

A vfurther objectfof the invention is .to provide a vnovel means -for cooling Athe internal surface oi abottle, jar or similar glass article so that va more 'vigorous vfluid coolant, such as a suitable gaseous fluid-liquid spray mixture, may be .ef"

y:iectively applied t lthe `internal surface of the .article from its bottom upward throughout fthe greater part of its height and a milder-coolant, such -as compressed air alone or mainly air, may be effectively Aapplied 'to the 4remaining upper partof theinternal surface ofthearticle.

Other robjects and advantages of ythe invention will'hereinaitefbe pointedout or will become apparent from the .following description of ,a practical embodiment of the invention as illustrated in the accompanyingY drawing, in which the view is a longitudinal verticalsection of anozzle structure Vof the ypresent invention in position for .use to eiiect coolingof the .internal surface of a bottle.

As shown in the drawing, thefnozzle provided by ythe present invention may comprise anfinner tubularmember I IJ lwhich may be closed at the free or Yforward end thereof, as at II. A second tubular member, designated I2, Vof greater di-V ,ameter ythan the .tubular member I0, surrounds the rearward end portionof the llatter and Vex- .rtendswiorwardly for vonly part of the length of the'vmember /IU. The tubular member i-2 may-be ,at that1 place, Awhereby tospacethetubular mem- -fber I2 from the '.innertubular member I Ii so as to :provide an vannular passage lI4 between these This passai-re I4 maybe fmade-fuid tight at its vforward end, as'by brazing the jinrturned forward end' portion I3 of the member Vl2 tothe inner tubular member 10. AAny other suitable known means may be employed tofasten the forward end of the tubular member `I2 tof-the `tubular member 'I0 to maintain `thesernenibers -inspaced concentric relation with-each other and so that ythe annular passagebetween them will Vbefclosed at its orwardfend.

=of cooling uid from the annular passage I4 may be discharged. These jet holes may be of any suitable total number, size or sizes, and relative arrangement that are deemed to be required or best suited forthe service intended.

'The invention provides a means forsupplying jets ofa suitable liquid, as water, to theinternal .passage or bore I6 of the inner tubular member fill. In the example shown, a liquid spray supply pipe ,I8 has a conveXo-concave forward lend wall I9 disposed in the rearward end of the vtubular .member I0 so that liquid spray, indicated at 22D,

from a spray hole 2| in the end wall I9, will be projected in agenerally forward direction in the internal passage or bore I6 of the tubular member I0. As shown, the pipe I8 may be aligned vwith the tubular member I0 and secured to the rearward end of the latter, as by brazing or welding at 22, so that 'the .liquid spray discharging forward end wall I9 will serve asa closure for `therearward end of the internal passage orbore I6 of the tubular member I0. Any other suitable fknown' lmeans may be employed to fasten these partstogetherand to maintain them in suitable operating relationship.

The tubular Amember Iii is provided at about ythe place at which liquid spray is discharged thereinto (from the supply pipe I8 with intake vair vopenings 23 through which streams of air orlcther gaseous fluid under pressure may enter the infternal passage orbore of thetubular VmemberHIil "to c omrningle with and Jcarry :forwardly .in the passage nI6 the liquid spray particles therein,

The .-ud discharging from the jet holes :I5- thus will be a mixture of air or gaseous uid underv pressure and minute particles of the liquid from the pipe I8.

As shown, the air intake openings 23 are arranged in a circular series around the tubular member I slightly in advance of the discharge end of the liquid supply pipe I8.

The tubular member I2 is provided with air intake openings 24 for supplying streams of air or other gaseous fluid under pressure to the annular passage I4 and through such passage to the jet holes Ii. According to the present invention, air from a common source may be supplied to both the air intake openings 23 in the inner tubular member Il! and the more forwardly located aii` intake openings 2d, in the tubular member I2. To this end, an outer air supply pipe is disposed in concentric spaced relation with the liquid supply pipe I8 and with the rearward Iend portion of the tubular member I2. An air supply passage 26 thus is provided within the air pipe around the liquid pipe I8 in open communication with the annular passage I4 of the pipe I2 at the rearward end of the latter. Air from the supply passage 2t thus may pass into the rearward end portion of the annular passage I4 whence some or all of such air may pass through the air intake openings '23 to the internal passage or bore I6 of the inner tubular member It for the purpose hereinbefore pointed out.

Some of the air entering the rearward end of the passage id may continue past the air intake openings 23 forwardly in the passage it for discharge through the jet holes l?. air supply passage 2&3 may have a forward reduced continuation air passage 2l located between the rearward end portion of the tubular member I2 and the surrounding portion of the air pipe 25. This continuation air passage 2li may be closed at a place forwardly of the air intake openings 2li, as by a closure ring or bushing 28 fitting between the pipe 25 and the member I2. As shown, there is another of these bushings or closure members, indicated at 29, between the parts 25 and i2. These bushings or closure members 28 and 29 serve to close the forward end of the continuation air passage 2l and to maintain the desired spaced concentric relation between the outer pipe or tubular member 25 and the tubular members therewithin. Obviously, these two bushings might be combined into but one bushing or any other suitable known means might be employed to close the passage 2l at its forward end and to connect the members 25 and I2 so as to maintain them in spaced concentric relation with each other.

The nozzle structure may be operatively supported by any suitable known nozzle supporting and operating means for locating the nozzle in position to project into the interior of an article of hollow glassware that is to be cooled and so that the air passage 26 and the liquid supply pipe i8 may be supplied with air and liquid as required for the cooling operation to be performed. The nozzle is shown in the drawing in position to effect cooling of the internal surface of a bottle 30. No means have been shown for operatively supporting the nozzle and the bottle in the positions shown. as such means may be readily provided. Such means may provide for a relative rotation between the article to be cooled and the nozzle, in which event the discharge portions of the inner tubular member ID and the intermediate tubular member I2 of the nozzle structure may However, the A have fewer jet holes than would be desirable or required in the absence of such relative rotation.

Operation of the nozzle shown to effect cooling of the internal surface of the glass article 30 in accordance with the method of the present invention will be readily understood. The jets of the cooling fluid-liquid spray mixture passing from the jet holes I5 into the bottle 3B against the internal surface of such article from its bottom upward for a predetermined, in this instance, the major part of the length of the bottle, will have a relatively greater cooling action than the jets of uid discharging from the jet hole I'I against the upper remaining part of the internal surface of the bottle. The latter jets may consist entirely, or mainly, of air or gaseous fluid. The air or other gaseous fluid jets will aid in effecting the desired cooling of the internal surface of the upper or neck portion of the bottle and will promote or aid emigration or outward passage of the gaseous fluid-liquid spray coolant from the lower portion of the article. This outgoing coolant will of course also serve to cool the upper or neck portion of the bottle.

It will be understood that the external surface of the bottle may be cooled by any suitable means, not shown, in coordination `with the internal cooling, especially when the cooling operation is to effect tempering of the bottle.

Many modications of the nozzle structure shown in the accompanying drawing and of the operation thereof herein described will readily occur to those skilled in the art.
